Reaction Steps

Compound 77(50 mg, 0.127 mmol) obtained in Example 77 was dissolved in water (1 mL) and 1,4-dioxane (1 mL), to the solution were added n-propylamine (14 μL, 0.176 mmol, 1.4 equivalents) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (24 mg, 0.127 mmol, 1.0 equivalent), and the mixture was stirred at room temperature for 4 days. The reaction solution was extracted with chloroform, and the extract was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography (chloroform:methanol=98:2 to 90:10) to obtain the title compound (25 mg, 45%).
